A multi-function handheld device comprising:
- a casing unit including a lower casing member and an upper casing member mounted on top of said lower casing member, each of said lower and upper casing members having a rear casing part and a front casing part that extends forwardly from said rear casing part in a longitudinal direction,
- said rear casing parts of said lower and upper casing members cooperatively confining an air chamber, and having rear ends that are distal to said front casing parts and that cooperatively define an air inlet in the longitudinal direction so as to be adapted to permit blowing of air into said air chamber, said rear casing part of said lower casing member being further formed with an air outlet that is disposed transverse to the longitudinal direction and that is adapted to permit releasing of the air that was blown into said air chamber, thereby permitting generation of a whistling sound output,
- said front casing part of said upper casing member being formed with a torch receiving chamber,
- said front casing parts of said upper and lower casing members being parallel to each other and being spaced apart in the transverse direction so as to define a receiving slit therebetween, said front casing part of one of said upper and lower casing members being formed with a mounting socket that is registered with said receiving slit, said front casing part of the other one of said upper and lower casing members being formed with a pivot stub that engages said mounting socket,
- said casing unit further having an outer wall surface formed with a thermometer receiving cavity and a compass receiving cavity;
- a torch unit disposed in said torch receiving chamber and including
- a battery set having a first battery terminal and a second battery terminal opposite to said first battery terminal,
- a lamp member having a first lamp terminal in electrical contact with said first battery terminal, and a second lamp terminal that extends adjacent to and that is normally spaced apart from said second battery terminal, and
- a press member mounted on said front casing part of said upper casing member and operable so as to urge said second lamp terminal to contact said second battery terminal and make electrical connection between said second lamp terminal and said second battery terminal;
- a planar mirror piece disposed in said receiving slit and having a peripheral frame portion mounted pivotally on said pivot stub;
- a planar magnifying lens piece disposed in said receiving slit and parallel to said mirror piece, said lens piece having an edge portion mounted pivotally on said pivot stub;
- each of said mirror piece and said lens piece being movable between a concealed position, where a corresponding one of said mirror piece and said lens piece is confined between said front casing parts of said upper and lower casing members, and an exposed position, where the corresponding one of said mirror piece and said lens piece is exposed from said front casing parts of said upper and lower casing members;
- a thermometer mounted securely in said thermometer receiving cavity;
- and
- a compass mounted securely in said compass receiving cavity, wherein the compass receiving cavity is located at the bottom of the lower casing member, below the torch unit, the magnifying lens, and the planar mirror piece.
